RAILWAY CAR BRAKE.

Application filed February 7,1927. Serial 10. 166,479.

I My present invention relates to brakes for railway cars and it has more particular reference to the manner of installing a highpower hand-brake upon a freight car of the hopper-bottom or dump-door type.

One of the primary Objects of the present invention is to provide means for mounting the gearing for increasing the power in conjunction with the ratchet device that prevent the reverse movement of the gearing during the application of the brakes. I have also provided a novel manner of mounting the gearing upon the end wall and supporting frame-work therefor. In connection with the ratchet device I have provided a housing for the gearing that is so designed that the brakeman will not have access to the ratchet devices excepting from a plane above the operating hand-wheel of the brake and thereby avoid the liability of the brakeman inserting his hand and arm though the wheel to manipulate the ratchet and thereby expose himself to injury. With the structure herein disclosed the hand-Wheel is rotated upon a horizontal axis as are also the gears for increasing the power, and the pull-chain or cable that connects the gearing, etc., with the brake-rods below the car extends downwardly to an idle pulley and then substantially.horizontally inwardly of the car to the brake rods. Other features of my invention are dependability of operation, durability of construction, simplicity and novelty in the arrangement of the parts, and economy in fabrication.

I prefer to carry out my invention and to accomplish the divers objects thereof in substantially the manner hereinafter fully described and as more particularly pointed out the claims, reference being made to the aceompany ipg drawings that term part o-l th spec ca on.

O a Figure l, a vertical elevation of an end portion railway car showing my irnrovements applied thereto with the gearing structure in edge elevation.

Figure 2, is a vetrical face view of the structure illustrated in Figure l, with the gearing structure in front elevation.

Figure 3, is a vertical elevation of a portion .of the end walls and supporting struc ture of the car to illustrate the manner of preparing the same for the installation of my gearing.

Figure 4, is'a vertical transverse section of the gearing structure, the view being taken on line H of Figure 2, and looking in the direction indicated by the arrows.

In the drawings, which are more or less schematic, I have illustrated a preferred or typical embodiment of my invention, and in said drawings I have employed similar reference characters to designate the same parts wherever they appear through the several views.

As before stated, the railway car is preferably of the hopper-bottom or dump-door type and comprises the usual underframe, which includes the end-sill 5, which is a channel beam positioned with its web in a vertical plane and its lateral flanges extended inwardly of the car as seen in Figure 1. The body of the car, which is supported upon the underframe, is shown only fragmentally, and consists of longitudinal vertical side-walls 6 and transverse vertical sidewalls 7 ofconsiderably less height than the side walls and from the lower edges of which the hopper sheets 8 slope or incline inwardly and downwardly the desired distance to provide the hopper-bottom of the body. Be cause of the peculiar construction of such freight-cars it is frequently undesirable to mount the brake mast on a vertical axis in the usual manner, and I have therefore materially shortened said mast and positioned it with its axis horizontal and at a right-am gle to the plane of the wall 7 of the carbody. In connection with the gearing I utihas the vertically disposed channel beam 9.

to assist in mounting the gear-housin and pulley. lfhe channel-beam 9 is vertically d' posed, with, its flanges extending outrorn the car and its ends are secured .ively to the end-sill 5 and the endwall 4 and the left-hand flange has a portion "ill cut away to permit of the insertion and mounting of a portion oi the gear-structure, as seen in Figure tl.

lhe gear-housing preferably comprises outer and inner or front and rear castings that are suitably assembled and provide means tor iournaling the gear elements, which latter I prefer to employ in the form shown in Letters "Patent l l'oi 1,508,564, is=

- ed T-shape when viewed in front elevation and consists of a horizontally elongated plate ll the ends of which are apertured to receive the bolts or rivets for securing the plate in position and the right-hand end portion projects through the cutaway recess in the vertically channel beam 9. A hearing is provided in the central portion oi the lower edge to receive the transverse pin -12 upon which the winding pulley 13 is secured and also the large gear i l of the gear ing heretoiore relerred to. Above the plane or the upper edge at pulley til the rear plate or the housing extends outwardly over the pulley as at 15 and then continues upwardly in a vertical direction to provide the flat upri ht extension 16 that is spaced from the wall 7 of the car and is provided. with side walls 17 thateatend back to the plane of the portion ll of the housing first described. A bearing 18 is provided in the upright portion it for the inner end oi tl e bralzernast 19 upon which latter is mounted the pinion member 5 10 of the power gear Lateral cars 21 project from the inner por tion of the sidewalls 17 oi" the casting in substantially the plane of the portion ll of the casting and are riveted to the vertical end-wall oi the car body and seen in Figures l and do I The side-wall 17 and the vertical plate 16 provide an enclosure into which the inner end or the bralremast projects and a ratchet wheel 22 is mounted upon the latter and is engaged by pawl 23 mountin upon a transverse or bolt 24 inserted t rough the up per portion of the vertical plate 16. As will be seen in Figures 1 and 4:, the front wall 16 extends above the plane or the pawl so that the latter is accessible solely from the top and sides and cannot be reached from the front. This prevents the bralreman inserting his hand and arm through the wheel 25 upon the must for the purpose of releasing the pawl when throwing 0d the brake, and the described construction compels him to operate the pawl from above or from the sides of the wheel.

Projecting horizontally from the inner or rear casting are so ental shaped flanges or walls 26 that aflor means for mounting the front or outer casting and which extend away from the end-wall 7 or the car to a plane beyond the vertical plane of the vertical plate 16, as shown in Figure 1. The outer or front casting consists of a plate 27 of substantially circular outline with a radial extension 28 that extends up in front of and guards the face of the pinion 20 and said plate 27 and its extension are provided respectively with bearings for the pin announce iii and mast A flange 29 projects in wardly from the edge of plate 2'? and the same is secured by rivets 30 to the segmental flanges 2b of the inner or rear casting.

The winding pulley 13 has one end of the chain 31 secured to it while the opposite end of said chain is secured to the proper bralre operating rod under the car. The chain extends downwardly from pulley 13 to and partly around an idle pulley 3% and then substantially horizontally inwardly ed the car The pulley 3% is partly enclosed within a guard 33 that has upper and lower lugs 34 that are riveted to the adjacent llangc of the vertical channel beam it and also has a lateral loot or lug 35 that is se cured to the top flange of the channel endsill of the underframe, thus securely mount ing and bracing said pulley against the up ward and inward pull of the chain during the application of the brake.

' What I claim is l. The combination with a railway-car including an underframe and a vertical endwall, of a brake actuating structure comprising a gear housing consistin of spaced front and rear members mounts upon said wall, a horizontally disposed brake-mast journaled in said housing members, gears mounted between said housing members and connected with said mast, a pawl and ratchet structure controlling said gearing and an extension projecting from one oi said housing members past said pawl and ratchet structures whereby the latter is in-' accessible in a horizontal direction from the front of the mechanism.

'2. The combination with a railway-car of a brake actuating structure comprising-a brake-mast and hand-wheel mounted at the end or said car and rotatable upon a horizontall axis gearing connected with said mast and with the brake mechanism, a pawl and ratchet structure controlling said gearing, and a housing for said gearing secured to the end of the car and provided with a portion that extends in front of and above said pawl whereby the latter is manually accessible solely around the edges of the housing extension.

3. The combination with a. railway-car havin an end-sill, a, vertical end-wall space above said sill and a post mounted on said sill and extended to and secured to said wall, of a gear-housing secured to said wall and the upper portion of said post, gears rotatable upon horizontal axes within said housing, means for actuating said cars, a chain connecting said gears to the rake mechanism, and a rotatable member mounted upon said sill below said housing and connected with said intermediate portion of said chain.
